<p style="text-align: justify; line-height: 1.20; margin: 8px 0 8px 0;">Let’s take a closer look at the contents of the <span style="font-weight: bold;">ELMA365-Overview</span> workspaces.</p>
|
||
<h2 class="p_Heading2"><a id="elma365-tab" class="hmanchor"></a><span class="f_Heading2">ELMA365 workspace</span></h2>
|
||
<p style="text-align: justify; line-height: 1.20; margin: 8px 0 8px 0;">Here you can see charts showing the state of processes in the system: requests from Front API and their processing time, requests to Web API, as well as statistics of script execution.</p>
|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;">If the values of indicators exceed the limits, scripts should be optimized.</p>
|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;"><img alt="elma365-overview-dashboard-2" width="992" height="418" style="margin:0;width:992px;height:418px;border:none" src="elma365-overview-dashboard-2.png"/></p>

<p>Note the CPU and memory consumption of pods, as well as the change of pods’ statuses for selected time intervals.</p>
|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;">If there is a sharp increase in resource consumption and their shortage, increase the number of resources and replicas, as well as the limits for pods. Then examine the service logs to identify possible causes of problems and fix them.</p>
|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;"><img alt="elma365-overview-dashboard-4" width="1083" height="492" style="margin:0;width:1083px;height:492px;border:none" src="elma365-overview-dashboard-4.png"/></p>

|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;">If you have deployed a standard Kubernetes cluster, install a high-load <span style="color: #0000ff;"><a href="preparing-optimized-kernel.html" class="topiclink">Linux system</a></span> to ensure optimal cluster performance.</p>
|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;"><img alt="elma365-overview-dashboard-5" width="1032" height="454" style="margin:0;width:1032px;height:454px;border:none" src="elma365-overview-dashboard-5.png"/></p>

<p style="line-height: 1.28; margin: 0 0 11px 0;">The most important chart in this workspace is <span style="font-weight: bold;">Stat activity</span>. It shows information about the current activity. If the chart value is close to the maximum (<span style="font-weight: bold;">Max Connections</span>), increase the <code><b>max_connections</b></code> parameter.</p>
|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;"><img alt="elma365-overview-dashboard-6" width="1163" height="230" style="margin:0;width:1163px;height:230px;border:none" src="elma365-overview-dashboard-6.png"/></p>

|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;">The <span style="font-weight: bold;">Messages per Queue</span> chart shows the messages in the queue. You can use it to determine which microservice is accumulating messages. If the number of messages does not decrease, reboot the corresponding microservice and examine the service logs using <span style="color: #0000ff;"><a href="install-loki.html" class="topiclink">Loki</a></span>.</p>
|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;"><img alt="elma365-overview-dashboard-7" width="1019" height="304" style="margin:0;width:1019px;height:304px;border:none" src="elma365-overview-dashboard-7.png"/></p>

|
||
<p style="line-height: 1.20; margin: 8px 0 8px 0;">To track database performance and efficiency, use the <span style="font-weight: bold;">Query Operations</span> chart. You can analyze various metrics related to query operations in <span style="color: #0000ff;"><a href="mongodb.html" class="topiclink">MongoDB</a></span>.</p>

<p style="text-align: justify; line-height: 1.20; margin: 8px 0 8px 0;">Note that the <span style="font-weight: bold;">Total Commands / sec</span> chart displays the total number of commands per second. It is used to monitor the performance and efficiency of the <span style="color: #0000ff;"><a href="redis.html" class="topiclink">Redis</a></span> cache. The chart also allows you to analyze various metrics related to command execution in Redis.</p>
|
||
<p style="text-align: justify; line-height: 1.20; margin: 8px 0 8px 0;"><img alt="elma365-overview-dashboard-9" width="1109" height="178" style="margin:0;width:1109px;height:178px;border:none" src="elma365-overview-dashboard-9.png"/></p>

|
||
<p style="line-height: 1.28; margin: 0 0 11px 0;">If the <span style="font-weight: bold;">HTTP Error</span> chart shows an increased number of errors, examine the Ingress Nginx logs to determine the cause.</p>
|
||
